Cemented carbide is known as an excellent tribo-material and therefore applied to mechanical seals, bearings, dies, and so on. Recently, the research on tribo-properties has become more important for the tribo-material development in accordance with needs of improved wear resistance and higher operation speed. In this study, effect of WC-3mass%TiC-2mass%TaC binder-less cemented carbide with dispersed modular carbon on tribo-properties was evaluated and considered. In the result, the effectiveness of frictional surface feature and self lubrication due to dispersed carbon on tribo-properties were found.
